An organic electroluminescence device is constituted by a pair of substrates each provided with an electrode, and an organic luminescence layer of an organic luminescence material and a liquid crystal layer of a liquid crystal material, respectively disposed between the substrates. The liquid crystal material has an isotropic phase transition temperature lower than a glass transition temperature of the organic luminescence material. The liquid crystal layer has been formed by disposing the liquid crystal material on the organic luminescence layer in an isotropic phase state at a temperature lower than the glass transition temperature of the organic luminescence material and cooling the liquid crystal material to a temperature lower than the isotropic phase transition temperature.
